Quickref is a global documentation project for Common Lisp. It automatically builds a website aggregating reference manuals for all Quicklisp libraries. The manuals are generated with Declt in Texinfo format, and then processed to HTML with Makeinfo.

Another System Definition Facility — de facto standard build system for Common Lisp software.
Includes UIOP, the Utilities for Implementation- and OS- Portability, a library to make possible the portable development of CL software.

Antik provides a foundation for scientific and engineering computation in Common Lisp. It is designed not only to facilitate numerical computations, but to permit the use of numerical computation libraries and the interchange of data and procedures, whether foreign (non-Lisp) or Lisp libraries. It is named after the Antikythera mechanism, one of the oldest examples of a scientific computer known.
